Application filed August 28, 1905. Serial K0. 276,099.

To all whom it may concern:

Be it known that I, ALnXANnnn MCLEAN, a subject of His Maj esty' the King of Great Britainand Ireland, residing at Brae Side, Ti Tree Point, in the Provincial District of Hawkes Bay, in the Colony of New Zea-- land, have invented certain new and useful Improvements in Protectors ior Pneumatic Tires for Motor- Cars and Similar Vehicles, of which the-following is a specification. I v p 7 i I This inventionprovides an improved protector for the pneumatic tires of. motor cars and similar vehicles.

- i According'hereto I. employ a ring oi semi-circular inaction, the inner periphery of the ring being of slightly larger diameter than the rim of the wheel upon which it is to be employed. i

The pneumatic tire closely fits the concavity of the ring.wl1ich revolves with it. Disk plates may be used to prevent dust from entering between the tire and the ring. I

Referring to the accompanying drawing,- Figure 1 is a side elevation partlyin section,

I Figure 2 asectional plan on A'-A, Figure 1, and Figure 3 a section of the tire and rim on a larger scale.

The vehicle wheel 1 of ordinary construction and having the usual pneumatic tire 2 is fitted with the protecting ring 3 which is semi-circular in section, as clearly shown in Figure 2; the concavity being of a shape to receive the pneumatic tire which'when infiated fits it closely. p v The inner diameter of the ring is slightly larger than the rim of the wheel so that the rim, with the tire deflated, may be placed within the ring and then Specification of Letters-Patent.

peripheries, into'corresponding recesses formed in the ring and are held in position by countersunkscrews 6.

A circular hole 7 is cut in the centre of each disk to clearvthe hub of the wheel. I When my invention 'is employed upon awheel of comparatively large diameter it-may be convenient to make the disks each in two or more sections, the

The protector is made of metalor other suitable material.

the radius of the curve of the cross section of the portion of the tire opposite-the ri'ng, whereby the tire touches the ring only along the center and the edges of the ring are free therefrom.
